Abstract
An exceptionally efficient operation is achieved through the use of orthogonal code divisional multiple access radio communication between a base station and a plurality of user handsets. Each user handset is provided with a local oscillator. The base station transmits a reference pilot/sounding signal which is received at the user handsets and the local oscillators at the user handsets are phase locked to the reference pilot/sounding signal.
